WILLIAM F. GAR'BE, OF FORT COLLINS, COLORADO.

RESERVOIR HEAD-GATE.

To all whom it may concern:

Be it known that I, WILLIAM F. GARBE,

' residing at Fort Collins, county of Larimer,

and State of Colorado, have invented certain new and useful Improvements in Reservoir Head-Gates; `and I do declare thefollowing to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invent-ion relates to improvements in headgates for regulating the flow of water from a reservoir.

My improved construction is more especially intended as a reservoir headgate,'or, Where the gate is of large size and subjected to considerable'pressure by reason of the column of water in the reservoir.

My object is to provide a headgate of this character which may be operated with comparatively little friction, and to this-endl the gate` is equipped with antifrictional rollers arranged on opposite sides thereof and engaging tracks formed upon the headgate frame on opposite sides of its opening. These tracks form an angle with the portion of the frame which is engaged by the gate proper when the latter is closed. For instance, if the tracks occupy a vertical position, the headgate seat is inclined, the

construction and arrangement being such.

that when the headgate is completely closed 'or occupies its lower-most position, it tightly engages its seat around the opening 1n the frame of the structure, but as soon as the gate begins to rise, it immediately leaves its seat, thus doing away with the friction which would otherwise exist during its opening or rising movement.

Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference being made to the accompanying drawing in which 'is trated an embodiment thereof.

`|In this drawing: Figure 1 lis a rside elevation, partly in section, showing my imillusproved headgate in the closed position.`

Figs. 2 and3 are horizontal sections taken on the line 2 2 and 3 3 respectively, of

Fig. 1. Fig. 4 is a view looking at one of the headgate pockets carrying t antifrictional rollersv with which the gate is equipped. In this View, a portion of the Specification of Letters Patent.

face plate which retains the rollers in place is broken away as well as a portion of the rubber gasket, which is applied to the plate for the purpose of forming a tight joint between the frame and the roller pockets and tracks. Fig.- 5 -is a horizontal section taken on the line 5 5, Fig. 1. Fig. 6 is a central, vertical section taken on the line 6 6, Fig. 2. Fig. 7 is a sectional view showing another form of roller pocket in which the rollers are connected by links.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate my improved headgate, tothe upper extremity of which is connected a stem 6, which passes through an opening in the top bar 7 of the gate and is secured in place by means of nuts 8. 'The upper portion of this stem is cogged, as shown at 9. Thiscogged rack of the stem is engaged by an operating gear 10, fast upon a shaft 12, with which is connected an operating crank or handle 13, which is employed in raising and lowering the gate.

The frame 14C surrounding the opening,

through which the water escapes from the reservoir, is provided with an inwardly-projecting flange 15, to which is applied a face plate 16, extending entirely around the opening 17 and forming a seat for a similar plate 18, applied to the face of thevgate. This frame 14 is set into cement or concrete 19. (See Figs. 1, 2, 3 and 6 of thepdrawing.) As shown in thedrawing, the face of the frame 14, occupies an inclined position, lying in a plane forming an angle with a vertical plane, in'which bearing lianges or tracks 2O lie, these tracks projecting outwardly from the .frame 14.- on opposite sides.

Applied to the opposite sides of the headgate are pockets 21, in which are located antifrictional rollers 22, which are located in a runway 23, with which each pocket is provided. This runway is closed except in front or adjacent the tracks 20, of the frame. Here the rollers are exposed andprotrude from the pockets sufliciently to engage the said tracks and form a bearing during the opening and closing movement ofthe headgate. It will be understood that during the act of raising and lowering the headgate, as well as at all other times when the headgate is in position, the exposed portions of the antifrictional rollers are in contact with the tracks of the frame. The rollers 22 are placed in the pockets from `the front and A are held in place by means of face plates 24,

which are secured in place by screws 25, or other suitable fastening devices. plates overlap journals 2G, formed on the opposite extiemities of the rollers 22, and therefore retain the latter in place. To the outer' surfaces of the plates 24, are applied rubber gaskets 27, whereby a tight joint is formed between the tracks 20 and the p'o'ckets. Each pocket is provided with a plate 28, projecting outwardly therefrom, these plates being provided with openings through which bolts 29 are passed, the said bolts being threaded in openings formed in opposite sides of the gate, whereby the pocket-s are firmly'secured in place.

The headgate is connected with the frameV 14 by means of metal straps 30, attached to the gate on opposite sides between the two pocket-plates 28. The inner extremities of the straps 30 are bent inwardly, as shown at 31, forming hooks which engage vertical grooves 32 formed in the opposite sides of the frame 14. These hooks loosely engage the grooves but retain the gate in operative relation with the frame.

- As illustrated in the drawing, each side of the headgate is equipped with two pockets. It is evident, however, that a single pocket or more than two pockets may be employed,

if desired, depending upon the size and` weight of the gate.

From the foregoing description, the use and operation of my improved reservoir headgate will be readily understood. It is evident that by turning the gear 10 in one direction the gate will be raised; while by turning the said gear in the opposite direction, the gate will be lowered. By virtue of the fact that the tracks 20 occupy a vertical position, while the seat surrounding the opening in the frame and adapted to be engaged by the headgate occupies a position inclined to the vertical, the face of the headgate adapted to engage the said seat being oppositely inclined, while the roller pockets are so arranged that the rollers on the exposed side of the pocket engage the tracks 20 of the frame during the entire opening and closing movement of the gate, as soon as the gate leaves its closed position, its face will move away from the seat on the frame, thus doing away entirely with friction between the face of the headgate and that portion of the frame engaged thereby. It will also be understood that during the closing movement of the gate, the seat face of the latter is constantly approaching the seat of the frame and when the gate occupies its lowermost position, the two seats are in contact. During the operation of the headgate, the ,rollers 22, in the pockets 21, protrude through an opening in the face of the pocket and act upon the tracks 20, in the frame, the resul friction causing the rollers to rEhese travel in a direction the reverse of the movement of the gate.

Attention is called to the fact that each pocket is provided with an outer wall 33, and a central core 34, there being a space between the outer surface of the core and the inner surface of the wall, constituting the roller runway in which the rollers travel during the operation of the gate.

1n further explanation of the operation of the gate, it may be stated that the reservoir, or the water which the gate is intended to control, is supposed to be at the left of the gate in Figs. 1 and 6, the shading at the left of Fig. 6 indicating the water in the reservoir, while the arrow in the same ligure indicates the direction of its flow through the opening 17 when the gate is open. Beyond the gate in the direction of the flow of the water and located at the right of the frame 14, in Figs. 1 and 6, the flume 35 is located, through which the water travels after leaving the reservoir.

In order that the downward movement of the gate may be interrupted at the proper time and that there may be a positive stop to such movement at the instant the gate is in the closed position, the frame is provided at its lower extremity with adjustable bolts 36, the heads of which form a stop or support for the gate, when the latter is in the closed position.

In Fig. 7 of thedrawing, the rollers 22 are connected by links 22A. In this view the core 34A is provided with a face plate 35, composed of hardened steel, whereby the life of the core will be greatly increased. At each extremity of the casing 36, above and below the exposed rollers is located a gasket 37 adapted to engage the track and exclude dirt and sand from the roller pocket. The plate 38 of the pocket is provided with slots 39 adapted to receive fastening devices (not shown), the slotted openings permitting the necessary degree of lateral adjustment.

Having thus described my invention, what I claim is:

1. A headgate having a pocket on each side of the gate in which is formed a runway, and antifrictional devices located in the runway, the antifrict-ional devices being ex- @esima vices exposed on the face of the gate, the opposite sides of the frame being provided with tracks adapted to be ,engaged by the antifrictional devices, the said tracks form ing an4 angle with the headgate seat formed on theframe, whereby as the gate is raised, its face will recede from the face of the frame; while during the closing movement'l of the gate, the face of the latter will approach the face of the frame, substantially as described.

4. In a. reservoir. headgate, the combination with a frame, of a gate connected in operative relation with the frame, the latter being provided with tracks on opposite sides, and the gate having pockets on opposite sides carryingantifrictional devices, which are exposed on the side of the pockets adjacent the tracks, whereby said devices engage the tracks and form antifrictional bearings for the gate during its movement in either direction, substantially as described.

5. A reservoir headgate, comprising a frame, a gate movably mounted adjacent the frame for opening and closing a passageway through the frame, the latter having tracks on opposite sides, and the headgate having antifrictional bearings on opposite sides engaging the said tracks, the face of the gate and the seat for the gate on the frame lying parallel with each other and extending at an angle to the tracks, which the antifrictional bearings engage, the face of the gate being arranged to move away from its seat on the frame during the opening movement of the gate and to approach the said seat during its closing movement, substantially as described.

6. A headgate provided with a pocket secured to each side of the gate, the said pocket containing antifrictional devices, which are exposed on one side of the pocket and free to travel therein, when in contact with an engaging device.

7 The combination with a frame having an opening therein, of a gate movably mounted to travel back and forth, adjacent to the said frame for o ening and closing the opening therein, an pockets carrying antifrictional devices, the said pockets being engage tracks with which the frame is provided, the said tracks occupying a position at an angle to the face of the gate and the seat for the latter on the frame, the arrangement being such that whenthe gate is closed, its face engages the seaton the frame which recedes therefrom constantly during the opening movement of the gate.

8. Thecombination with a frame, of a headgate movably mounted adjacent the frame and provided on each side with a pocket carrying antifrictional devices,- the said pocket comprising an outer shell and an inner core forming a runway having parallel runs in the front and rear and curved runs connecting with parallel runs at both extremities, the runway being open onthe side adjacent the frame, whereby the antifrictional devices protrude from the runway for engagement with tracks with which the frame is equipped, the face of the gate and the seatV therefor on the frame occupying planes forming an angle with the plane of the said tracks, the arrangement being such `that as the gate 1s opened, its face recedes from the seattor the frame, and approaches the latter during its closing movement, substantially as described.

9. A headgate provided with a pocket secured to each side of the gate, said pocket containing antifrictional rollers connected by links, the rollers being exposed on o ne side of the pocket and free to travel therein.

10. A headgate provided with a pocket secured to each side of the gate, the said pocket havin a core provided with a plate face, antifrictional devices located inD the ocket and links connecting the said devices or the purpose set forth. f
